What is Le Chatelier’s Principle?
Le Chatelier’s Principle states that if a system at equilibrium is subjected to a change (such as temperature, pressure, or concentration), the system will adjust itself to counteract that change and restore equilibrium.
Le Chatelier’s Principle states that if a system at equilibrium is subjected to a change (such as temperature, pressure, or concentration), the system will NOT counteract the change.
